Helical Gear Reductor

A gear reducer is a mechanical system of gears in an arrangement such that the input speed can be lowered to a slower output speed but have the same or more output torque.

What is a Helical Gear Reductor?

The operation of a gear reducer involves a set of rotating gears that are connected to a shaft with a high incoming speed, which is sent to a set of rotating gears where the speed or torque is changed. How many gears are in a gear reducer assembly is dependent on the speed requirements of the application.

The use of a gear reducer occurs when the drive gear is smaller and has fewer teeth than the driven gear. This is unlike the condition where the drive gear is larger with more teeth than the driven gear, which is referred to as overdrive. Gear reducers are an essential component in cars and trucks where the high rotational speed of the engine is converted such that the slower motion of the tires can interpret and use the power safely.

How Gear Reducers Work

Gear reducers, or reduction gears, are necessary for high-efficiency machinery operating at elevated speeds. For the speed produced by the machinery to be practical, it has to be reduced to a lower speed to meet the needs of the powered application. The basic construction of a gear reducer consists of a large gear that is positioned with a smaller gear with both gears turning together.

In the case of a single gear reducer where a large gear is connected to a single smaller gear, the smaller gear makes two turns for every one turn of the larger gear. With the multiple turns of the smaller gear, there is greater speed but a loss of torque.

The gear reduction process takes place at preset ratios that meet the characteristics of the input and output gears. A gear reducer achieves the change in energy by changing the ratio of the moving gears.
